Title: Improvements in castors and in their application to vehicles
IPC: B60B33/02
Filed: 1939-02-03
Abstract: 525,957. Castor-wheel mountings, TOWNSEND, C. R. and TOWNSEND, C. M. Feb. 3, 1939, No. 111. [Class 108 (ii)] [Also in Group XXXIV] Means for simultaneously braking the swivelling movement of a castor and the rotation of the castor wheel comprises a non-rotatable brake member which is moved axially to engage a friction member usually carried by the fork, the movement of the friction member effecting the application of a brake to the wheel. As applied to a trolley the wheel fork 1 is mounted between ball-bearings 5, 6 on a fixed cap 7 and a nut on the fixed peg 28. A slotted bar 10 slidable on a pin on the fork 1 is connected to the cranked end 15 of the operating cam arm 16 of an internal expanding brake the shoes 21 of which engage an annulus 24 of the wheel 2. A non-rotatable brake member 27 is slidable on the peg 28 to engage a friction block 13 on the bar 10 thus preventing swivelling movement of the fork 1 and applying the brake 21 to the wheel. As shown in Fig. 3 the member 27 is engaged by a spring 29 and is disengaged by a cable 33 but when as in Fig. 1 the brakes of two castors are operated simultaneously the members 27 may be connected to a bar 34 operated by a cable 41 from the trolley handle 42 which is pivoted at 43 on brackets 45 the arrangement being such that the brakes are applied by the springs when the handle is released. The application springs may be arranged between the part 35 and the trolley frame.

Title: Improvements in and relating to the inhibition of sprouting of potatoes during storage
Inventor: NULTSCH WILHELM
IPC: B01J19/00
Filed: 1960-01-02
Abstract: The sprouting of potatoes during storage is inhibited by treating them with a composition comprising at least one non-toxic compound having the general formula:  <FORM:0897143/I/1> in which Ar represents an aryl group e.g., containing one or more substituent halogen atoms and/or nitro and/or alkyl groups, R represents a hydrogen atom or an alkyl group and R1 represents an alkyl group.  Ar may represent benzene or naphthalene.  The composition may also comprise a non-toxic diluent such as powdered talc or a liquid, such as etholene glycol, in which the compound dissolves containing, if desired, an emulsifying dispersing and/or wetting agent, liquid compositions may be applied as sprays or aerosols.  The following non-toxic compounds may be used: benzene sulphone-N-monoethylamide, benzenesulphone-N-di-isopropylamide, 3-nitrobenzenesulphone-N-dimethylamide, 3-chlorobenzenesulphone-N- monopropylamide,2, 4, 5-trichlorobenzeneosulphone-N-methyl-or dimethyl-amide, 2, 4, 5-trichlorobenzenesulphone -N-diethylamide, 2, 4, 5-trichlorobenzene sulphone-N-di-isobutylamide, 3-chloro-4-methl-ben zene sulphone-N-dimethylamide, 2-nitro-4-methylbenzenesulphone-N-dimethylamide, 3-nitro-4-methylbenzene sulphone-N-monomethylamide, a -naphthalenesulphone-N-dimethylamide.

Abstract: 1528461 Knitting-machines KROY KNIT TING DEVELOPMENTS Ltd and B Y (SIMULATED FURS) Ltd 24 Dec 1975 [3 Jan 1975] 200/75 Heading D1C For knitting high-pile fabric on a multifeed circular machine needles are preselected in advance of each carding head 16 and then undergo a reselection at the actual head so that certain needles are lowered after picking- up less than a full load of fibres or some needles which were initially inactive are raised to pick-up fibres, thereby forming tufts of different density more closely to simulate animal furs. The preselection, e.g. by cams and an overriding pattern drum, selects needles 14 to take fibres and 12 to remain inactive at the head. Then predetermined needles 14 are lowered or needles 12 raised at predetermined positions along head 16 to vary the fibre pick-up. Slivers of contrasting fibres may be fed to the head and the reselection of needles used to produce a fabric with contrasting tufts, e.g. in stripes. The reselection may be accomplished by a tricked pattern wheel 20, or by the patterning unit disclosed in the Specification of application 55798/74.

The arcs a, b of the driving notches 16 and of the lenticular shoes 19 of the bobbin carriers are curved to the radius of the discs. The guidance of the bobbins is effected entirely by the driving notches 16 and the edges of the apertures in the top plate. Some of the corners 17 are rounded off as shown. The shoes 19 are composed of two gapped plates which fit loosely around the pin 22 and are fixed together in situ by riveting &c.

Abstract: 431,568. Gas fires. TENNANT, D. R., Braemar, Quarry Lane, Appleton, near Warrington, Lancashire. Jan. 9, 1934, No. 732. [Class 126] Vertical radiants are retained in position in a gas fire by means of a rod 3 or its equivalent, spaced from and extending across the fire back, to which it is secured at its ends, the rod passing through an opening in the head of each radiant. In Fig. 3 the radiants are provided with open-topped slots 2 and the rod 3 which engages in them is secured in apertures 4 in the side walls of the back, and of substantially the cross-section of the rod. In modifications, the slots 2 are open at the bottom instead of the top, or are closed at both top and bottom. The rod may be supported in vertical slots 4, Fig. 1, in the side walls, in which case the holes in the radiants may substantially fit it. In cases where holes, and not slots, are provided in the radiants the ends of the rod may be carried in open-topped slots in projections or attachments on the side walls, so that it may be lifted out from the fire with the radiants carried on it, thus avoiding the necessity of withdrawing it laterally in order to replace a radiant. A chain or close-coiled spring may replace the rod.

Title: Improvements in or relating to gas blast electric circuit interrupters
IPC: B61L3/22
Filed: 1959-01-08
Abstract: 854,254. Gas-blast switches. WESTING- HOUSE ELECTRIC CORPORATION. Jan. 8, 1959 [Jan. 10, 1958], No. 733/59. Class 38 (5). A gas-blast switch has a moving contact 9 and a fixed nozzle contact 8, the gas blast exhausting through the nozzle into a chamber 16 where the rise in pressure causes the separation of isolating contacts 10, 11. The Figure shows two of the above interrupting and isolating units extending from a high-pressure reservoir 3 carried by an insulating pedestal 4. To open the switch, a valve 38 is actuated so as to connect the space between pistons 17 to the lowpressure region within the pedestal 4. The high-pressure gas in the reservoir 3 acts through apertures 49 on the outer faces of the pistons 17 and causes them to move against the bias of a spring 18 to open the contacts 9. When the pressure in each chamber 16 is sufficient, a piston 20 is moved against the bias of a spring 22 to move the contact 10 to its open position and to move a valve element 27 to a position in which it closes the vent 25 from the cylinder 21 containing the piston 20. When the valve 38 is restored to the position shown, the space between the pistons 17 is connected to the reservoir 3 so that the spring 18 moves the contacts 9 back to their closed position, but the pressure in the chambers 16 maintains the isolating contacts 10, 11 open. A valve 55 may be operated to vent the pressure from the chambers so that the springs 22 may close the isolating contacts 10, 11.

[Also in Division B7] Mechanism for controlling two apparatuses, e.g. a rudder and the pitch of a tail-mounted propeller of a helicopter, comprises a control input rod 76, e.g. connected to a rudder bar 25, leading to two bell-cranks 65, 66 pivoted respectively at 67, 68, the output movement of the two cranks being varied by a lever 33 moving output rods 77, 78 along the crank. The movement of these rods is transmitted to the apparatuses through levers 57, 58, 60, 61 to rods 62, 64. The lever 33 also rotates cam-plates 34, 35 having followers connected to the levers 60, 61, one follower being moved on each side of the neutral position shown. In operation the lever is moved to one extreme position or the other, moving one of the rods 77, 78 to the pivot 67 or 68 of the bell-crank, and the control 25, 76 then only affects the other bell-crank and the rods leading from it to one apparatus. At the same time, movement of the cam-plates causes the other apparatus to be adjusted to a predetermined position. In its application to a helicopter, for example, in the " hover " position, the rudder is fixed at about 70 degrees to the longitudinal axis, and yaw control is effected by propeller pitch changes, and in the " high speed position," the pitch is fixed and the rudder is movable by the rudder bar 25. In another embodiment (Fig. 5, not shown), the cam-plates 34, 35 are replaced by two arms depending from the lever 27, each connected by a rod directly to a lever 51 or 52.
